Vancouver, Canada – May 22, 2019 – Endeavour Silver Corp. (NYSE: EXK; TSX: EDR) reports multiple high-grade silver-gold intersections in the Plateros and San Miguel veins from the 2019 drill program at the Bolanitos mine in Guanajuato, Mexico. A total of 19 holes were drilled to mid-April, of which 12 holes intersected high grades over mineable widths and an additional 4 holes intersected old mine workings (view longitudinal sections for Plateros and San Miguel here).
Drilling highlights in the San Miguel vein just north of the Bolanitos plant include 58 grams per tonne (gpt) silver and 22.1 gpt gold for 1827 gpt silver equivalent (Ag Eq calculated at an 80:1 Au:Ag ratio) over a 3.5 metre (m) true width (53.3 oz per short ton (opT) AgEq over 11.5 feet (ft) in hole MG-10). New high-grade vein mineralization has now been delineated over a 250 m length by 130 m depth below and northwest of the old San Miguel mine workings, still open to the northwest.
Drilling highlights in the Plateros vein just west of the Bolanitos plant include 108 gpt silver and 4.25 gpt gold for 448 gpt Ag Eq over a 2.3 m true width (13.1 opT AgEq over 7.5 feet (ft) in hole PLU-20). New high-grade vein mineralization has now been delineated over a 250 m length by 120 m depth below the Plateros mine workings where Endeavour is currently mining, still open at depth and to the southeast.
Bradford Cooke, Endeavour Director and CEO, commented, “We continue to be encouraged by our positive exploration results at Bolanitos. Recent drilling has extended high grade silver-gold mineralizaiton in both the Plateros and San Miguel veins, which should help to replace reserves, increase resources and extend the mine life at Bolanitos.”
“Our operations group are nearing resolutions to the elevated arsenic in certain ores and reduced equipment availabilities, both of which put mine development and production behind schedule in Q1, 2019. We plan to provide a full operational review for shareholders late this month.”
Drilling highlights are summarized in the following table of drill results.
